PUPPET-VALVE.

Specification of Letters Patent.

Patented Oct. 16, 1906.

T0 @ZZ whom it may concern:

Be it known that I, TIMOTHY STEBBINS, a citizen of the United States,and a resident of Davenport, in the county of Scott and State of Iowa,have invented certain new and useful Improvements in Puppet-Valves, ofwhich the following is a full, clear, and exact specification.

My invention relates to puppet-valves for pumps; and its object is toprovide means for retaining the said valve in operative relation to itsseat in such manner that both the valve and said retaining means can beinserted down into the well from above round and secured in place orremoved thereirom for repairs, according as desired; and its object isalso to provide a valve which will lift from or drop into its seatwithout the possibility of binding either in its open or shut position.This I accomplish by the means hereinafter fully described and asparticularly pointed out in the claims.

In the drawings, Figure 1 is a vertical section of a coupling in whichthe valve-seat of the puppet-valve is located, showing my improvementsapplied thereto. Fig. 2 is a transverse section thereof, taken on dottedline 2 2, Fig.' l. Fig. 3 is a side view of a -modified form of valvecapable of use in connection with said retaining means. Fig. 4 is a-transverse section taken on dotted line 4 4, Fig. 3, looking in thedirection of the arrows.

Referring to the drawings, A represents a coupling which connects thesections of thewell-pipe a above the puppet-valve in which the lowercylinder of the pump is located and the well-pipe below the same. Aboutits center of length this coupling is provided with aninwardly-projecting flange if, which restricts the bore of the well andhas the valve-seat B screwed into the restricted opening made thereby.This valve-seat is cylindrical from its lower to Vnear its upper end b,which latter extends above the iiange 7c and is made thicker, so as tofurther reduce the valve-opening. The outer circumference of thisupwardly-extending portion b is undercut, substantially as shown. Thevalve engaging this seat B comprises a circular plate c of a diametersufficient to cover said seat and has its under side faced with leatherd or other suitable material. Projecting centrally upward from plate cis a stud e, whose lower cylindrical portion is smooth and whose upperportion is screw-threaded. This stud e projects up throughv a suitablecentral guide opening in the boss C of a spider, which has three or morecorresponding equidistant inverted L -shaped legs DD, the inner edges ofwhich serve as guides for the circumferential edges of the plate c ofthe valve and, together with the engagement of the guide-opening of theboss of the spider by the stud e thereof, insures the movement of thevalve in a vertical plane to and from the valve-seat. The inner surfacesor edges of the legs D are provided with a convexed double bevel forminga kind of foot F, and as said legs are cast of a metal having a certaindegree of elasticity when the valve is lowered by some means, such asthe lower end of the plunger or a pipe into whose lower extremity it isscrewed until it closes the valve-opening, the extremities of the legssnap over the outer inverted beveled edge of the valve-seat and areretained thereby sufliciently tight to hold the 'spider in such positionas to confine the valve and guide the reciprocations of the same in themanner hereinbefore described.

v In view of the fact that when it is desired to release the valve afterit has been inserted in place it is necessary tounscrew the means bywhich it was lowered from 'stud e, and it is desirable to prevent thespider from revolving with'it I provide the outer circumference of thevalve-seat with a stop-lug I, which one of the legs of the spider willengage and prevent further revolution thereof should the friction of thevalve have a tendency'to turn it.

In Fig. 3 of the drawings I showa modified form of the valve. I In thismodification the plate f is constructed the same as plate c,hereinbefore referred to, except that it is provided with a centralscrew threaded opening G, which extends longitudinally up into its studg. A rubber packing-ring 7L 1s placed a ainst and is secured to theunder side of p ate f and is secured thereto by a disk PI, that has ascrew-threaded stud H', which screws up into the screwthreaded centralopening G in plate f until said packing-ring is clamped between it andsaid plate f. Projecting downward from this disk are wings y', whichextend in planes at right angles to each other and intersect at a pointin alinement with the axis of stud H. These IOO wings extend downthrough the valve and serve as an additional means to direct themovements of the valve.

What I claim as new is 1. In a well the combination with a valveseathaving an undercut outer circumference, and a puppet-valve having avertical stud arising therefrom, of a spider engaged by said stud andhaving legs that spread over and inclose said valve and are providedwith enlarged lower ends that engage the undercut portion of thevalve-seat whereby said spider is removably retained in proper positionto confine and guide said valve.

2. In av well the combination with a valve- Seat having an undercutouter circumference, and a puppet-valve having a vertical stud arisingtherefrom, of a spider having a perforated boss engaged by said stud andhaving legs that spread over and inclose said valve and are providedwith enlarged lower ends that engage the undercut portion of thevalveseat whereby said spider is removably retained in proper positionto confine and guide said valve.

8. In a well the combination with a valveseat having an undercut outercircumference, and a puppet-valve having a vertical stud arisingtherefrom, of a spider engaged by said lstud and having legs that spreadover and inclose said valve and have their extremities .provided withenlargements that interlock with the undercut portion of saidvalve-seat.

4;. In a well the combination with a valveseat having an undercut outercircumference, and a puppet-valve having a vertical stud arisingtherefrom, of a spider having a perforated boss engaged by said stud andhaving legs that spread over and inclose said valve and have theirextremities provided with enlargements that removably interlock with theundercut portion of the valve-seat.

5. In a well the combination with a valvesea-t having an undercut outercircumference, and a puppet-valve having a vertical stud arisingtherefrom, of a spider engaged by said stud and having elastic legs thatspread over and inclose said valve and are provided with enlarged lowerends that engage the undercut portion of the valve-seat whereby saidspider is removably retained in proper posiltion to confine and guidesaid valve.

6. In a well the combination with 'a valveseat having an undercut outercircumference, and a puppet-valve having a vertical stud arisingtherefrom, of a spider having a perforated boss engaged by said stud andhaving elastic legs that spread over and inclose said valve and areprovided with enlarged lower ends that engage the undercut portion ofthe valve-seat whereby said spider is removably retained in properposition to confine and guide said valve.

7 In a well the combination with a valveseat and a puppet-valve having avertical stud arising therefrom, of a spider engaged by said stud andhaving legs that spread over and inclose said valve and have the inneredges of their extremities provided with a convexed double bevel andinterlock with said valve-seat.

S. In a well the combination with a valveseat and a puppet-valve havinga vertical stud arising therefrom, of a spider having a perforated bossengaged by said stud and having legs that spread over and inclose saidvalve and have the inner edges of their extremities provided with aconvexed double bevel and removably interlock with the valve-seat.

9. In a well the combination with a valveseat and a puppet-valve havinga vertical stud arising therefrom, of a spider engaged by said stud andhaving elastic legs that spread over and inclose said valve and have theinner edges of their extremities provided with a convexed double beveland interlock with said valve-seat.

10.- In a well the combination with avalveseat and a puppet-valve havinga vertical stud arising therefrom, of a spider having a perforated bossengaged by said stud and having elastic legs that spread over andinclose said valve and have the inner edges of their extremitiesprovided with a convexed double bevel and removably interlock with thevalve-seat.

In testimony whereof I have hereunto set my hand this 25th day of July,A. D. 1905.-

TIMOTHY 4 STEBBINS.
